Chapter 2, Problem 21C

Write a program that consists of three classes, A, B, and C, such that B extends A and that C extends B. Each class should define an instance variable named “x” (that is, each has its own variable named x). Describe a way for a method in C to access and set A’s version of x to a given value, without changing B or C’s version.

Data Representation Part 3 HW3 1. Convert each decimal number to its 9's complement (use as many digits as shown): a) 73 b) 40512 c) 980034 d) Perform subtraction using 9's complement: 5042-671 2. Convert the following decimal numbers to the 10's complement: a) 128 b) 4097 c) 56020 d) Perform subtraction using 10's complement: 3205-4879 3. Perform the following multiplications. Assume that all values are unsigned numbers. (No problem with unsigned (always positive) numbers, just use the same standard techniques as in base 10.) a) 10112 × 01012 b) 011012 × 001112 c) 1100102 × 10112 d) 10110102 x 111012 4. Perform the following multiplications. Assume that all values are signed 2's complement numbers. a) 11002 01112 b) 00102 x 10102 - first multiply without sign-extending (show the wrong result), then redo with proper sign-extension. c) 111002 × 000112 5. Perform the following divisions. Assume that all values are unsigned numbers. a) 1011012 ÷ 1102 b) 1000112 ÷ 1012
